Superstar athletes Tiger Woods and Lindsey Vonn have been dating since November, the pro golfer and Olympic skier having found time in their packed schedules to vacation this month in Antigua, according to HollywoodLife.com.

An unidentified "source close to Lindsey" told the website that the two "met through the ski community, because Tiger is an active skier. Lindsey has been teaching Tiger’s kids, Sam and Charlie, how to ski.”

An anonymous "Tiger source" added that even though Woods, 37, and Vonn, 28, are often on separate continents, "they constantly talk on the phone. And Tiger has made more of a commitment to Lindsey lately—he’s pulling out all the stops.”

Vonn, who is recently divorced from skier Thomas Vonn, told The Denver Post in December that she and Woods "are just friends" when the two were in Vail, Colo., at the same time: “My brother was the ski instructor for his kids this November in Vail. Guessing that’s where it came from.”

But, according to a golf.com story, Woods and Vonn were in Salzburg, Austria, at the same time earlier this month.

His spokesman has said Woods won't comment on the issue, and Vonn's publicist released this statement, according to the Los Angeles Times: "Lindsey is currently in the midst of the World Cup season in Europe. Her focus is solely on competing and on defending her titles and thus she will not participate in any speculation surrounding her personal life at this time."
